ABSTRACTA study was undertaken to determine typical concentration of airborne bacteria and fungi (microflora) in Enugu State University of Science and Technology (ESUT) in the tropical rainforest environment of Nigeria. Aerial sampling was conducted at various faculties and departments each day. The air samples were collected thrice daily. Concentrations of airborne microflora exceeded available local guidelines for classroom, lobby, library and offices, but not in the restricted ...
CHAPTER ONE 1.1 INTRODUCTION Plants have provided a source of inspiration for novel drug compounds, as plant derived medicines have made large contributions to human health and wellbeing. Plant extracts have been used for a wide variety of purposes for many thousands of years (Jones, 1996). The antimicrobial activity of plant oils and extracts has formed the basis of many applications, including raw and processed food preservatives, pharmaceuticals, alternative medicine and natural therapies ...
Abstract Soaps and other cleansing agents have been around for quite a long time, a medical document from about 1500 B.C. shows that Egyptians combined animal and vegetable oils with alkaline salts to form a soap-like material used for treating skin diseases, as well as for washing and Scrubbing body or hands. The objective of this study is to evaluate the potency and the antibacterial activity of medicated soap and Natural plant extracts used to make soaps against some selected common hum...
ABSTRACT The antibacterial activity of three types of medicated soap on Staphylococcus aureus isolated from wound infections was conducted. Fourteen individuals with wound infections were sampled. Swab sticks were used to collect specimens from wound infections; each swab stick was streaked separately over plates of nutrient and mannitol agar and subsequently incubated at 370c. Out of the fourteen (14) individuals sampled, 5(36%) were infected with Staphylococcus aureus, Pseudomonas aerugin...
ABSTRACT The strategy of utilizing mechanochemical synthesis to obtain metal-organic frameworks with high surface area and nanodisperse particles has been espoused. Transition metal ions have been shown to form complexes with organic moieties such as benzyl-N,N-dimethyldithiocarbamate. It has been established that iron in its oxidised state (Fe3+) is cidal to microorganisms and dialkyldithiocarbamates have an established antifungal activity, the complex of Fe3+ and benzyl-N,N-dimethyldithioc...
ABSTRACT This study reviewed the importance of hand washing and health benefits derived from the practice and also highlighted the consequences of not observing strict hand washing practice. Swabs from primary school pupils showed cfu mean total viable count of 1.60 x 104, 1.50 x 104, 1.60 x 104 and 1.7 x 104 across the four schools. Salmonella spp., Staphylococcus spp. and E. coli were the most sensitive microbes to the antibiotics used while Ciprofloxacin and Gentamicin were active across t...
ABSTRACT Milk has been known to be highly nutritive ad thus a good medium for bacteria growth and vehicles for transmission of food borne infection. A total of 16 samples of different brands of bagged milk obtained from some selected markets within Kaduna metropolis were analyzed for the occurrence of bacteria using pour plate method on selective media. The total aerobic count ranged from 4.0 x 103 to 2.8 x 106. The result obtained showed that bacteria (Staphylococcus aureus) in bagged milk a...
1.0 INTRODUCTION 1.1 BACKGROUND OF STUDYSchistosomiasis is a chronic human disease caused by parasitic flatworms called schistosomes or blood flukes. The schistosomes live i1n the blood vessels associated with the intestine and urinary bladd1er where they reproduce sexually.Schistosomiasis is one of the most wide spread parasitic disease that put about 400-600 million people worldwide at risk and has already infected about 200 million people. The disease is endemic in 74 countries of the worl...
ABSTRACTThis study was carried out to investigate the nutritional value and the antibacterial activity of bitter kola, (Garcinia kola). The result of the proximate analysis shows that bitter kola contains 51.95% moisture, 5.55% Ash, 9.75% crude fibers, 4.65% crude fat, 7.35% crude protein and 20.85% carbohydrate. The anti-bacterial activity shows that bitter kola can inhibit the E. coli and Staphylococcus aureus with diameter zone of inhibition of 14mm and 16mm respectively. There was no inhi...
INTRODUCTION1.1 Background of studyJuice is a liquid that is naturally contained in fruit and vegetables. It can refer to liquid that are flavoured with these or other biological food resources such as a beverage or used as an ingredient or flavouring in food, (Lewis, 2002), fruit juice is produce by squeezing or crushing fruit.Many fruit have cultivated since ancient times, (Waderiboldaji et al, 2008). There are many indigenous species at fruits such as the claries, which originated f...
ABSTRACTGastro Intestinal Helminthiasis was investigated among primary school children in Ihengwu village, Oko between February and March 2015. Sixty samples of freshly collected faeces from sixty randomly selected primary school children between the age of four and ten years from two selected primary schools; Gaius Benton and Pope John primary schools, Oko were analyzed. A small quantity of each faecal sample was collected from the specimen bottle and emulsified on a clean microscopic slide ...
ABSTRACTThis study was conducted to examine the fungi present in spoilt onion bulb. Five different sample of spoilt onion bulb were blended together and suspended in sterilized distilled water which was used to inoculate Sabouraud dextrose agar (SDA). Four different fungi were isolated from the sample and the morphological characteristics shows that the isolate belong to the following genera: Alternaria sp., Aspergillius sp., Penicillium sp., and Rhizopus sp. These fungi may have been respons...
AbstractThe ectoparasitic infestation of free range domestic fowls were surveyed between August and November, 2014. A total of 105 ectoparasites belonging to four species of two genera were collected. These were made up of three lice and one ixodid tick. The percentage occurrence of these parasites are: Menacanthus stramineus (50.5%), Rhipicephalus saguineus (29.5%), Damalinia ovis (12.4%) and Lipeurus caponis (7.6%). Lice were the most prevalent and predominant of the ectoparasites of the 35...
ABSTRACT The microbiological assessment of Garri, sold in two different markets in Benin City metropolis, was carried out using the pour plate technique.
